Yeah, plus if it's all just generated in a big lump, you tend never to 
really understand it the same as if you'd written it yourself by hand.  In 
the short term it's easier but in the longer term you end up scratching 
your head more, and wasting more time trying to understand what's been 
generated!  Like reading somebody elses sloppy code!

I find the best way is to whip up a quick and dirty perl script (or
bash/sed/awk, whatever) to mangle the data out of whatever form it's in
and turn it into something I can paste into the config.  It sounds old
fashioned, but you would be surprised how often we export from whatever
data source (usually windows-based, like Maximizer, ugh) to a flat text
comma-delimited file, then just mangle that out into a series of config
entries using perl.  We only do this infrequently tho (once every few
months) and it only takes me half an hr or so each time.  Sure beats data
entry!!

Bout the same for us.  Next step is trying to implement something with
net::ssh::perl that logs in and restarts services that fail, somehow
linked to event handlers.  Anyone had experience with this?  Could
check_by_ssh be given some creative commandline arguments?

Luke.
